Question

A solution contains Mg2+ions, Fe2+ ions and Cu2+ ions. On passing an electric current through this solution which ions will be the first to be discharged at the cathode. Write the equation for the cathode reaction. no spamming

Answer 1

Cu2+ ions will be deposited at cathode.

Cu2+(aq) + 2e- --> Cu(s) ( reduction )

Answer 2

Answer: Cu2+

Cu2++2e=Cu
